FOLDING CAMP-STOOL.

Application filed June 21, 1915.

To all whom it may concern:

Be it known that I, MARVIN V. BAXTER, a v

citizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented new and usefulImprovements in Folding Camp- Stools, of which the following is aspecification.

My invention relates to a folding camp stool and in particular to a campstool in which the movable parts are made of heavy steel wire.

It is an object of my invention to devise a folding camp stool which isextremely light in weight yet strong and durable, simple of constructionand easy of operation.

Another object of my invention is to construct a folding camp stoolwhich can be folded twice upon itself so that it is very convenient fortransportation, being easily carried about by hand or packed away as itoccupies in its folded condition but little space.

These and other objects of the invention will appear as the descriptionproceeds and will be pointed out in the claims.

In the accompanying drawings which form a part of this specification Ihave shown a convenient and practical embodiment of my invention and inwhich like reference numerals indicate like parts throughout the severalviews.

Figure l is a perspective of the folding 4 camp stool in its openposition. Fig. 2 shows a front View of the same when it is almostclosed. Fig. 3 shows a perspective of a modified form of the camp stool.Fig. 4 shows a frontal elevation of the same in its folded position.Fig. 5 shows a side view of the same in its folded condition.

On a horizontal metal rod 10 are pivoted a pair of diagonal supportingmembersv 11 and 12 which are preferably made of heavy steel wire. Thesediagonal supporting mem- J bers are of the general shape of a rectanglebut their longest sides are slightly bent outwardly as at 1415 wherethey connect with the smaller sides in order to provide a larger baseand seat, respectively. The wire of thediagonal supporting members isbent to form an eye at the middle of the long sides which pivotallyengage the outer ends of horizontal rodlO. Two sets of collars 16 and 17secured to rod 10 adjacent to the eyes engaging said rod retain saideyes in their seats on the rod. A foldable seat is Specification ofLetters Patent.

secured to the upper short sides of the diagonal supporting members inany preferred manner. I have shown the same to consist of canvas but itis obvious that any other suitable material may be used and even hingedsolid seat members may be substituted therefor.

The bottom side of the diagonal member 11 is provided with a pair ofrecesses or notches equi-distantly spaced from the ends thereof. Thesenotches are preferably made by bending the wire at these places slightlyupwardly. A U-shaped bottom brace 18 extends inwardly from the shortside of diagonal member 11 and is secured thereto by means of eyesformed on the outer ends of the legs thereof which pivotally engage thenotches in the bottom side just referred to. The bottom side of diagonalsupporting member 12 is provided with similar notches which are engagedby a U-shaped bottom brace 19. The inner ends of the legs of brace 19are bent upon themselves to form eyes 20 which engage the transversemember of the U-shaped bottom brace 18, as clearly shown in Fig. 1. Ipreferably bend the wireof which bottom braces 18 and 19 are madeslightly upwardly at the place where the same engage the bottom sides ofthe diagonal supporting members 11 and 12 thereby forming a small notchor recess adapted to hold the transverse member of U-shaped lateralsupports 21 and 22, respectively, in position when the camp stool isin'its open position, as shown in Fig. 1. The U-shaped lateral supports21 and 22 extend vertically downward from the upper sides of thediagonal supports to which they are pivotally secured. The width of thelateral supports is approximately equal to that of the bottom braces,thereby securing a firm structure, preventing any lost motion when thecamp stool is in its open position.

It will be understood that any load placed on the seat will tend tospread the diagonal supportingmembers apart. This tendency is opposed bythe bottom braces 18 and 19 which limit the outward movement of thediagonal supports. The lateral supports 21 and 22 are held in positionnot only by the notches on bottom braces 18 and 19, respectively, butalso by the tendency of the diagonal supports to move outwardly, whichin turn firmly holds the bottom braces in a horizontal extendedposition.

In Fig. 3 I have shown a modification of my camp stool which is similarto' the construction of the camp stool shown in Figs. 1 and 2 with theexception of the diagonal supports and the lateral supports. Each of thediagonal supporting members is composed of two sections 11 and 11 and12. and 12 which are U-shaped in form, the outer end of the legs formingan eye pivotally engaging the horizontal rod 10 at its outer ends. Eachof the lateral supports is likewise made of two sections, 21 and 21 and22 and 22 The upper sections 21 and 22 are made of a lengthcorresponding to that of the sections of the diagonal supportingmembers. In forming the trans verse member of the U-shaped uppersections 21 and 22 the wire is bent upon itself form ing a pair of eyes23 to which links 24: are secured at one end and which'engage the eyesformed at the outer ends of the legs of the lower section of the lateralsupport.

When it is desired to fold the camp stool it is only necessary to pressthe lower ends of lateral supports 21 and 22 inwardly toward each other.The ends will move toward each other and in doing so will lift the innerends of the bottom braces l8-19 upwardly while at the same time thediago nal supporting members swinging on their pivots will approach eachother and the camp stool will occupya folded position, as shown in Fig.2. It should be noted that the 7 camp stool shown in Fig. 2 has not yetreached its extreme folded position. The diagonal members may be made toapproach each other until they lie in close contact with one another.

The modified camp stool shown in Figs 35 allows not only of the foldedposition just described but also allows the diagonal supporting membersand the lateral supports to be folded upon themselves by reason of thesectional construction of said members. When folded, as shown in Figs. 4and 5, one pair of links 2 f will be above and the other pair of links24 will be below the horizontal rod 10, as shown in Figs. 4C and 5.

I claim:

1. In a folding camp stool, the combination of a frame made of steelwire, said frame comprising a central horizontal rod, diagonalsupporting members pivoted to the outer ends of said rod, said diagonalmembers being of the shape of a rectangle, the short sides thereofforming the top and bottom, respectively, a folding seat extendingbetween the upper sides of said diagonal supporting members, av pair ofU-shaped bottom brace members, said brace members being pivoted at theends of the lateral sides thereof to the bottom sides of said diagonalmembers at points spaced equi-distantly Copies of this patent may beobtained for members at points equi-distant from the ends thereof, thewidth of said lateral mems bers corresponding to that of said brace-members, the transverse sides of said lateral members passing below andengaging the ends of said brace members adjacent to the bottom sides ofsaid diagonal members.

2. In a folding camp stool the combination of a frame made of steelwire, said frame comprising a central. horizontal rod, diagonalsupporting members pivoted to the outer ends of said rod, said diagonalmembers being ofthe shape of a rectangle, the short sides thereofforming the top and bottom, respectively, a folding seat extendingbetween the upper sides of said diagonal members, a pairof U-shapedbottom brace members pivoted to the bottom sides of said diagonalmembers,the transverse sides thereof being in interlockingengagementwith each other, a pair of vertical lateral U- shaped supporting memberspivoted to the upper sides of said diagonal members, the

transverse sides of said lateral memberspassing below and engaging theends of said brace members adjacent to the bottom sides of said diagonalmembers.

3. A folding camp stool comprising the combination of a frame made ofsteel wire, said'frame comprising a central horizontal rod, diagonalsupporting members pivoted bottom, respectively, a folding seatextending between the upper sides of said diagonal members, a pair ofU-shaped bottom brace members pivoted to the bottom sides of saiddiagonal members, the transverse sides of said brace members being ininterlocking-engagement with each other, a pair of upper lateralU-shaped supporting members pivoted to the upper sides of said diagonalthe lower lateral supporting members with the inner ends of said upperlateral supporting members.

In testimony whereof I have signed my name to this specification.
